Suicide is a public health crisis in the United States and around the world. Despite decades of research, prevention efforts have not substantially influenced suicide rates. Theoretical foundations for research are essential in building the science of suicide prevention. This article analyzes and evaluates the most recently published suicide theory based on an ideation-to-action framework, the Three-Step Theory of Suicide (3ST). This theory demonstrates significant scope and context as well as coherent content. Suggested theory improvements include enhanced clarity and directions for testability. Empirical evidence supports the merits of this theory, although further research is needed for population-specific application.
自杀在美国乃至全球都是一场公共卫生危机。尽管经过了数十年的研究，但预防措施并未对自杀率产生实质性影响。研究的理论基础对于构建自杀预防科学至关重要。本文基于一个从想法到行动的框架——自杀三步理论（3ST），对最近发表的自杀理论进行了分析和评估。该理论展现出了显著的范围和背景以及连贯的内容。建议的理论改进包括提高清晰度和可测试性的方向。实证证据支持了该理论的优点，不过针对特定人群的应用还需要进一步研究。
